JFET BF545A N-channel -30 V, +30 V 6.5 mA 250 mW SOT 23 NXP

N-channel symmetrical silicon junction field-effect transistors in a SOT23 package.

Low leakage level (typ. 500 fA)
* High gain
* Low cut-off voltage (max. 2.2 V for BF545A).
Applications
* Impedance converters in e.g. electret microphones and infra-red detectors
* VHF amplifiers in oscillators and mixers.
